Finding Irrigation Solenoids and Valves – There are generally two
accepted methods to find a lost solenoid/valve. The first method is to
connect the red lead of the transmitter to the station wire leading to
that valve and the black to ground as described above. We refer to
this as the 'unbalanced' method. Operate the Pro881™ as above and
begin your locate. When you reach the valve/solenoid location the
signal will expand into a large (approx. 2-4 ft.) diameter area of signal.
Many times, this signal volume will get louder. This is your indication
that you are over a valve or solenoid.
The second method starts by tracing the wire path as previously
described. Once the wire path has been traced you must power the
transmitter off, remove the black lead from earth ground and connect
it to the common wire. We call this the 'balanced' method. In the case
of multiple common wires, it is suggested that you isolate and connect
to the common wire that services the target valve. Connecting
multiple commons will work, however it weakens the signal response.
Power the transmitter on and adjust the output signal to suit the
situation. High power output is not usually necessary and will lessen
battery life. It is advised that you once again point the receiver at the
transmitter to assure that both units are on and functioning properly.
Slowly follow the pre-marked wire path. There will be an absence of
signal response due to cancelling of the closely parallel wires until you
near the valve. As you move closer to the valve the receiver will begin
making a chattering sound which will intensify and distort, turn the
volume down and take your time.
Even with the volume at its lowest setting the response of the valve
solenoid will be very loud. Pinpointing the exact location of the
